11. Handling Cautions
11-1) Mounting of module
a) Please power off the module when you connect the input/output
connector.
b) Please connect the ground pattern of the inverter circuit surely. If the
connection is not perfect, some following problems may happen possibly.
1.The noise from the backlight unit will increase.
2.The output from inverter circuit will be unstable.
3.In some cases a part of module will heat.
c) Polarizer which is made of soft material and susceptible to flaw must be
handled carefully.
d) Protective film (Laminator) is applied on surface to protect it against
scratches and dirt. It is recommended to peel off the laminator before
use and taking care of static electricity.
11-2) Precautions in mounting
a) When metal part of the TFT-LCD module (shielding lid and rear case) is
soiled, wipe it with soft dry cloth.
b) Wipe off water drops or finger grease immediately. Long contact with
water may cause discoloration or spots.
c) TFT-LCD module uses glass which breaks or cracks easily if dropped or
bumped on hard surface. Please handle with care.
d) Since CMOS LSI is used in the module. So take care of static electricity
and earth yourself when handling.
11-3) Adjusting module
a) Adjusting volumes on the rear face of the module have been set optimally
before shipment.
b) Therefore, do not change any adjusted values. If adjusted values are
changed, the specifications described may not be satisfied.
11-4) Others
a) Do not expose the module to direct sunlight or intensive ultraviolet rays
for many Hours.
b) Store the module at a room temperature place.
c) The voltage of beginning electric discharge may over the normal voltage
because of leakage current from approach conductor by to draw lump
read lead line around.
d) If LCD panel breaks, it is possibly that the liquid crystal escapes from the
panel. Avoid putting it into eyes or mouth. When liquid crystal sticks on
hands, clothes or feet. Wash it out immediately with soap.
e) Observe all other precautionary requirements in handling general
electronic components.
f) Please adjust the voltage of common electrode as material of attachment
by 1 module.
